Question

5. There is a circular pond and footpath runs along its boundary. A man walks around it,
exactly once, keeping close to the edge. If his step is 44 cm long and he takes exactly
600 steps to go around the pond, what is the radius of the pond?
​

Answer 1

Answer:

4200 cm or 42 m

Step-by-step explanation:

$Circumfrence \: of \: pond= 44×600=26400cm$

$2\pi \: r = 26400$

$2 \times 22 \div 7 \times r = 26400$

$r = 26400 \times 7 \div 44$

$r = 4200cm$
